Abstract

This paper describes a novel system termed Supercover Concrete for reinforced concrete which should significantly reduce or eliminate the incidence of reinforcement corrosion. It involves providing nominal covers to the steel reinforcement of 100 mm and introducing glass fibre reinforced plastic (GFRP) rebars in the cover zone to control surface crack widths. Short term loading tests on single span, simply supported reinforced concrete beams made using this design show that GFRP rebars are effective in controlling crack widths to limits laid down in current structural design codes. More oyer, the structural strength and the deflections which occur are not adversely affected. Results of preliminary tests to determine the long term performance of this design are also reported.
